MAINTENANCE AND SERVICE
610Engine oil
For the recommended service intervals and war-
ranties to be applied, an approved engine oil
must be used. Volvo recommends: If the engine oil is not checked regularly and the
level becomes low, this could cause serious
engine damage.
CAUTION
To satisfy the requirements for the engine's
service intervals, all engines are factory-filled
with a specially adapted synthetic engine oil.
Great care has been put into the choice of oil,
with consideration given to service life, starta-
bility, fuel consumption and environmental
impact.
For the recommended service intervals to
apply, an approved engine oil must be used.
Only use the prescribed oil grade to top off or
change the oil. Otherwise, there is a risk of
the vehicle's service life, startability, fuel con-
sumption and environmental impact being
affected.
Failure to use engine oil of the prescribed
grade and viscosity could cause damage to
engine-related components. Volvo Car Corpo-
ration disclaims warranty liability for such type
of damage.
Volvo recommends entrusting oil changes to
an authorized Volvo workshop.
Volvo uses different systems to warn if the oil
level is too low/high or the oil pressure is low. On
engine variants with an oil pressure sensor, awarning symbol is displayed in the instrument
panel when oil pressure is low . On engine
variants with an oil level sensor, the warn-
ing symbol in the instrument panel and display
messages are used to alert the driver. Some
engine variants have both systems. Contact a
Volvo retailer for more information.
Change the engine oil and oil filter according to
the schedule specified in the Warranty and Main-
tenance Records Information booklet. Oils of a
higher grade than that specified may be used. If
the vehicle is driven in adverse conditions, Volvo
recommends using an oil with a higher grade
than that specified.

Checking and filling engine oil
The engine oil level is monitored by an electronic
oil level sensor. Filler pipe
12
.
It may be necessary to top up engine oil between
regularly scheduled services.
No action is necessary with regard to engine oil
level until a message appears in the instrument
panel.
WARNING If this symbol is shown together
with the message
Engine oil level
Service required, visit a workshop – an authorized Volvo workshop is
recommended. The oil level may be too high.
CAUTION If this symbol is shown together
with a message about low oil level,
for example
Engine oil level low
Refill 1 liter, fill only with the indi-
cated volume, e.g. 1 liter (1 quart).
WARNING Do not spill oil on the hot exhaust pipes as
this could cause a fire.
Viewing oil level in the center displayThe oil level can be viewed using the electronic
oil level gauge in the center display once the
vehicle has been started. The oil level should be
checked regularly.
1.
Open the Car status app from App view in
the center display.
2. Tap Status to display the oil level. Oil level graphic in the center display.NOTE
The system cannot directly detect changes
when the oil is filled or drained. The vehicle
must have been driven approximately 30 km
(20 miles) and have been stationary
5 minutes on a level surface and with the
engine off before the correct oil level will be
displayed.
12
Engines with an electronic oil level sensor do not have a dipstick.

NOTE
If the conditions for measuring oil level are
not properly fulfilled (time after engine shut-
down, vehicle inclination, ambient tempera-
ture, etc.) the message
No value available
will be shown in the center display. This does
not mean that anything is wrong in the vehi-
cle systems.

• Ignition modes (p. 427)
• Vehicle status (p. 602) Refilling coolant
Coolant helps keep the combustion engine at
the right operating temperature. The heat trans-
ferred from the engine to the coolant can be
used to warm the passenger compartment.
When refilling coolant, follow the instructions on
the package. Never fill the cooling system with
only water. The risk of freezing is increased with
too low or too high amounts of coolant.
If there is coolant under the vehicle, smoke from
the cooling system, or if more than 2 liters (about
2 quarts) of coolant has been added to the sys-
tem, there could be something wrong with the
cooling system and starting the vehicle could
damage the engine. Call a tow truck and do not
attempt to start the engine.
WARNING The coolant may be very hot. Never unscrew
the cap when the coolant is hot. If coolant
must be filled, unscrew the expansion tank
cap slowly to relieve overpressure. Coolant expansion tank.

CAUTION
Only a modern battery charger with controlled
charge voltage should be used to charge the
starter battery. The rapid charging function
should not be used as this could damage the
battery.
NOTE
If both the starter battery and the hybrid bat-
tery are discharged, both batteries must be
charged. In such cases, it is not possible to
charge only the hybrid battery first.
The starter battery must have a certain level
of charge for it to be possible to charge the
hybrid battery.
CAUTION Failure to observe the following could cause
the infotainment energy save mode to tempo-
rarily stop working and/or a message in the
driver's display regarding the state of charge
of the starter battery may be temporarily
incorrect after an external starter battery or
battery charger has been connected:
• The negative battery terminal of the vehi-
cle's starter battery must never be used
to connect an external starter battery or
battery charger – only the vehicle's neg-
ative charging point should be used as
a grounding point.NOTE If the starter battery becomes discharged too
many times, it will shorten its service life.
The service life of the starter battery is affec-
ted by several factors, such as driving condi-
tions and climate. The starting capacity of the
battery reduces gradually over time. The bat-
tery must therefore be recharged if the vehi-
cle is not used or a long period of time or if it
is only driven short distances. Severe cold fur-
ther limits the starting capacity.
To keep the starter battery in a good condi-
tion, the vehicle should be driven at least
15 minutes per week or the battery should be
connected to a battery charger with automatic
trickle charging.
A starter battery that is always kept fully
charged has the maximum service life.
